What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Performance/Effectiveness - Improvement in Qualify of Life scoring (OAB)
Time Frame: 3 months
To demonstrate an improvement in Overactive Bladder Quality of Life using the International Consultation of Incontinence Questionnaire Overactive Bladder Qualify of Life (ICIQ-OABqol): questions in each subscale are scored by a summed range of 0 to 100, with a higher score indicating better quality of life. Overall score ≥ 10 points from baseline to follow-up is indicative of a clinically meaningful improvement.
3 months
Adverse event reporting (Safety)
Time Frame: 3 months
Device related, procedure-related and all serious adverse events
3 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Performance/Effectiveness - Improvement in Qualify of Life scoring (OAB)
Time Frame: 12 months
To demonstrate an improvement in Overactive Bladder Quality of Life using the International Consultation of Incontinence Questionnaire Overactive Bladder Qualify of Life (ICIQ-OABqol): questions in each subscale are scored by a summed range of 0 to 100, with a higher score indicating better quality of life. Overall score ≥ 10 points from baseline to follow-up is indicative of a clinically meaningful improvement.
12 months
Performance/Effectiveness - Improvement in Qualify of Life scoring (FI)
Time Frame: 12 months
Cleveland Clinic Florida - Fecal Incontinence Score (CCF-FIS): scores range from 0 for full continence to 20 for complete incontinence. A higher score is indicative of the severity of fecal incontinence. Assessed if participant had a score of ≥6 at baseline.
12 months
